To aZZ lg'lw'vri it may concern: lie t known that. I, Jorrr'r L. Mo-HUN, a. c tizen of fthe' United States, residing at Brooklyniin thecountyj'of Kingsand citagte I of New. Y ork, ha.ve imented a; certain ndw and useful Iinprovementin Car-Roof Structures, 'of which improvement the following 15 a specification, Y

1,077,631, dated November -'i,' l913, and one of the objects of invention is to provide an improved join't construction between theroofing sheets and the drain trough at the end portions oi the-latter over the side plates mi rushed in height tol' provideadditional Anotl-ier objectis'yte provide improved means 'fo-r 'fasteningjthe'end of the cap over V j the discharge lend 'ofithe trough at -,.the side f fror' 'r 'he-sideplateto' provide' ampleclear ance for thejdischa' r'ge o f-drain' waterfrom erebythe end of. the cap". issp'aced In the accompanying drawing: *Eigure l is atransife'rsesectio n o-ta portion of my improved car roof at theside'plate ofthe car; Fig. 2, aside elevation of the same; the cap section and; the roofing sheet at one side being removedlt oishow the trough con struction and the foim, ofjointbetween the trough and the edge of the roofing sheet; Fig. 3, a plan of the same with the cap section in place; and F igs; 4, 5, and 6, transtrough, roofing sheets and cap, taken on V (B -6, respectively 0 ig. 1. v -As shown in the drawings, my improvement is applied in connection with that type '45 of car roof in \vhiclr'a transverse drain trough, 12, is employed and the metal-roofing sheets, 7, extend transversely across the car with their adjacent side edges located over said drain trough. The metal drain trough is preferably U shaped in cross section having vertical side walls and the lat oral edges of the roofing sheets, 7, are turned up to form a \fQl'tiCal portion, 7", and a lateral flange 7, extending over the top of the-trough to sulistantiallv the center line,

reoessfor receiving the wider and shallower end portion, 12, of thetrough. ,The-s'hallow flanges, 12, of the troughmaybe'turn ed and the bottom of the trough-is preferably extended at 12, upon the top surface of the facia, 16, which is secured totheside plate The metal roofing sheets, 7, preferablyzexte'nd trans 'ersely from eaves to -ezives vof-athe.

the con Shing' Side walls .of the trough; over tl iesi he' The drain trough and'the of the roofing sheets are cover d inverted U shaped section with higoad lateral flanges resting upon'the roofing sheets,

and for the purposepf holding down the caps and roofingsheets, the caps are provided with down-turned end flanges, 14,

overhanging the sidesof the car and secured to the side plates. My-improved means for fastening thecap sections in position comprises a bridge piece, 17, spanning the discharge end of the trough and having lugs at its ends adapted to bear against the side plate. The bridge piece is placed just be neath the end flange, 1-1, of the cap section, 13, and both are securely fastened in position by means of bolts, 18, extending through the'cap' flange and the bridge into theside plates, The'cap flanges is thus spaced from the side plate and ample clearance is aflorded under the bridge piece for the discharge of water from the drain trough. The corner of the down-turned end flange, 8, of the roofing sheets may be cut out as indicated in Fig. 2, in order to clear the bridge piece, 17, at the point where the-same is bolted to the side plate, thereby allowing for a slight relative movement between the roofing sheets and the side frame of the car.

It will now be apparent that by means of this improved construction, wherein the lateral drain troughs are provided with flaring end portions having their side Walls diminishing in height over the sideplates, additional clearance is obtained at the eaves of the car without obstructing the flow or restricting the discharge capacity of the drain troughs. 7

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

ing flaring end portions with diminishing side walls extending down over the side of the side plates of the car, and metal roofing sheets extending transversely of the car and having their adjacent side edges located over said drain trough, the lateral edges of the roofing sheets at the flared portion of the trough having flanges turned up and over said diminishingside walls.

2. In a car root, the combination of a transversely located metal drain trough having flaring end portions with diminishing side .walls extending down over the side of the side plates of the car, and metal roofing sheets extending transversely of the car and having their adjacent side edges located over said drain trough, the lateral edges of the roofing sheets at the flared portion of the trough having flanges turned up and over said diminishing side Walls, and a metal cap covering said trough and having down turned end flanges spaced from the side of the car.

3. In a car roof, the combination of a transversely located metal drain trough having flaring ends portions with diminishing side walls extending down over the side of the side plates of the car, the side plates being notched'to form a recess for the flared ends of said trough, and metal roofing sheets extending transversely of the car and having their adjacent side edges located over said drain trough, the lateral edges of the roofing sheets at the flared portion of the trough having flanges turned up and .over said di minishing sidewalls.

4. In a car roof, the combination of a transversely located metal drain trough having flaring end portions with diminishing side walls extending over the side plates, metal roofing sh ets extending transversely of the car with their adjacent side edges located OVBI said trough and having end flan esextending down over the side plates of the car, the lateral edges of the roofing sheets having flanges turned up and over said diminishing side walls of the trough, and a metal cap covering said trough and having down-turned end flanges spaced from the side plates of the car.

5. In a car roof, the combination of a transversely located metal drain trough having end portions extending over the side plates, metal roofing sheets extending transversely of the car with their adjacent side edges located over said trough -and having end flanges extending down over the side plates of the car, a metal cap covering said trough and having end flanges turned down over the side platesgbridge pieces spanning JOHN L.
